On-the-fly note generation and a musical instrument

摘要

A method and apparatus for performing music on an electronic instrument in which individual chord progression chords can be triggered in real-time, while various individual notes of the chord, and/or possible scale notes and non-scale notes to play along with the chord, can be generated from separate fixed locations on the instrument, and in different octaves. The method of performance involves the designation of a chord progression section on the instrument, then assigning chords or individual chord notes to this chord progression section according to the defined customary scale or customary scale equivalent of a song key. Further, as each chord is played in the chord progression section, various individual notes of the currently triggered chords can be generated from separate fixed chord locations on the instrument, and in different octaves. Fundamental and alternate notes of each chord can be generated from separate fixed chord locations on the instrument for composing purposes, and in different octaves. Possible scale notes and/or non-scale notes to play along with the currently triggered chord, can also be generated from separate fixed locations on the instrument, and in different octaves. All performance data can be stored in memory or on a storage device, and can later be retrieved and performed by a user from one or more fixed locations on the instrument. The performance data may also be performed using a variable number of input controllers. Further, multiple instruments of the present invention may be used together to allow interaction among multiple users during performance, with no knowledge of music theory required.
